Set of eight organ pipes to make a major scale.

3D32.10 • B+50+20

diagram for demo

Vibrating Air Columns: Organ Pipes. These organ pipes can be played individually. They reproduce one octave of the Major scale. The relative lengths of the pipes are in exact proportion to the frequency ratios of the notes.
